Answer:
see below
Step-by-step explanation:
5 and 8 are not congruent because they are Same Side Interior angles. 12 and 13 are congruent because they are alternate exterior angles and 9 and 11 are congruent because they are corresponding angles. As for 1 and 16 we know 1 = 6 bc they are vertical angles, 6 = 14 and 14 = 16 bc they are corresponding so that means 1 and 16 are congruent.
